Few hardware vendors have not yet launched their own mini laptop (or, "netbook"). Most brands these days produce their own version of the same hardware, with Intel's i386-compatible Atom cpu's and Windows XP installed on a spinning hard drive or sometimes still a solid state disk. Some Linux models are still sold by some vendors, among whom Asus, which more or less started selling in this OLPC-inspired genre of laptops.

I don't know about an official Flash Player from Adobe yet, although I've heard MIPS Technologies has signed an agreement with them to port their latest player to MIPS. In the meantime Gnash works, I can watch Youtube videos with it, but support for other flash applications is probably less mature.
